Summary:
When presenting an instance of a UIPopoverController more than once from a subview, the presenting button does not get deallocated.  This only happens when running on iOS 7.0 or later.

Steps to Reproduce:
Using the Allocations tool in Instruments, I was able to reproduce this issue and will provide a sample Xcode project with instructions.

1. Add a subview which contains a UIButton (this button presents a UIPopoverController).
2. Select the button to present the popover.
3. Dismiss the popover and remove the subview.
4. Using the Allocations tool in Instruments, observe that UIButton gets deallocated.
5. Add the subview for a second time.
6. Select the button to present the popover.
7. Now dismiss it and present the popover for a second time.
8. Now remove the subview again.
9. Observe that the UIButton does not get deallocated.

Expected Results:
The button which invoked the presentation of the UIPopoverController should be deallocated after its subview has been released from memory.

Actual Results:
The button which invoked the presentation of the UIPopoverController was NOT deallocated and remains in memory.

Version:
iOS 7 or later

Notes:


Configuration:
This occurs on iOS 7.0 or later; Simulator and all versions of iPad
This does NOT occur on iOS 6
